If you have a set of christmas lights that is on a series circuit, predict what would happen if the series circuit were cut off in the middle. how would this differ from what would happen with a parallel circuit?

Prior to the invention of a revolutionary means of travel, people had to take long, dangerous journeys to cross parts of the country. Due to this development, society was revolutionized as travel became safe and efficient.

A 28.5-g object moving to the right at 18.5 cm/s overtakes and collides elastically with a 12.5-g object moving in the same direction at 15.0 cm/s. Find the velocity of each object after the collision. (Take the positive direction to be to the right.
